Question

I am working with a Windows Forms application in C# and Visual Studio 2005.

I am showing a message box within an button click event,

string messageBoxText = "Click OK to save your changes\n";
string caption = "Confirm Changes";
MessageBoxButtons button = MessageBoxButtons.OKCancel;
//Display the MessageBox
MessageBox.Show(messageBoxText, caption, button);

MessageBoxResult result = MessageBox.Show(messageBoxText, caption, button);

The following error pops up on compilation:

Error 1 The type or namespace name ‘MessageBoxResult’ could not be found (are you missing a using directive or an assembly reference?)

Also, IntelliSense does not show any such thing as MessageBoxResult. I have seen this statement on MSDN. How to capture the response of the message (OK/Cancel) without using MessageBoxResult?

Answer 1

The MessageBoxResult Enumeration is only available on .NET 3.0+. You’re using 2.0.

Use DialogResult as Walt suggested.
